为什么我的QT程序不能运行？（在线等！）
我的程序如下： #include <QApplication>
 #include <QPushButton>
 int main(int argc, char *argv[])
 {
  QApplication app(argc, argv);
  QPushButton hello("hello QT!");
  hello.resize(100,30);
  hello.show();
  return app.exec();
 }


编译过程:qmake -project
  qmake
  make
我用的不是交叉编译，Makefile内容如下：#############################################################################
# Makefile for building: qt
